„Connecting a trailer
T Trailer brakes
If your trailer’s total weight (trailer weight
plus its cargo weight) exceeds 1,000 lbs
(453 kg), the trailer is required to be
equipped with its own brake system. Elec-
tric brakes or surge brakes are recom-
mended, and must be installed properly.
Check that your trailer’s brakes conform
with Federal, state/province and/or other
applicable regulations. Your SUBARU’s
brake system is not designed to be tapped
into the trailer’s hydraulic brake system.
Please ask your SUBARU dealer and pro-
fessional trailer supplier for more informa-
tion about the trailer’s brake system. T
Trailer safety chains
In case the trailer hitch connector or hitch
ball should break or become disconnect-
ed, the trailer could get loose and create a
traffic safety hazard.
For safety, always connect the towing ve-
hicle and trailer with trailer safety chains.
Pass the chains crossing each other un-
der the trailer tongue to prevent the trailer
from dropping onto the ground in case the
trailer tongue should disconnect from the
hitch ball. Allow sufficient slack in the
chains taking tight-turn situations into ac-
count; however, be careful not to let them
drag on the ground.
For more information about the safety
chain connection, refer to the instructions
for your hitch and trailer. T
Side mirrors
After hitching a trailer to your vehicle,
check that the standard side mirrors pro-
vide a good rearward field of view without
significant blind spots. If significant blind
spots occur with the vehicle’s standard
side mirrors, use towing mirrors that con-
form with Federal, state/province and/or
other applicable regulations. T Trailer lights
yAdequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
yDo not directly connect your trail-
er’s hydraulic brake system to the
hydraulic brake system in your
vehicle. Direct connection would
cause the vehicle’s brake perfor-
mance to deteriorate and could
lead to an accident.
Always use safety chains between
your vehicle and the trailer. Towing
a trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch ball
damage.
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’s electrical
system and cause a malfunction of
your vehicle’s lighting system.

Driving tips 8-23
– CONTINUED –
Connection of trailer lights to your vehi-
cle’s electrical system requires modifica-
tions to the vehicle’s lighting circuit to in-
crease its capacity and accommodate wir-
ing changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals, the brake
lights and parking lights each time you
hitch up. T
Tires
Make sure that all the tires on your vehicle
are properly inflated to the pressure spec-
ified on the tire placard located on the driv-
er’s side center pillar.
Trailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer manufacturer’s
specifications. „
Trailer towing tips
TBefore starting out on a trip
y Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. y Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable. y Check that the tire pressures are cor-
rect. y Check that the vehicle and trailer are connected properly. Confirm that
– the trailer tongue is connected prop-
erly to the hitch ball.
– the trailer lights connector is connect-
ed properly and trailer’s brake lights illu-
minate when the vehicle’s brake pedal
is pressed, and that the trailer’s turn sig-
nal lights flash when the vehicle’s turn
signal lever is operated.
– the safety chains are connected prop-
erly.
– all cargo in the trailer is secured safe-
ty in position.
– the side mirrors provide a good rear-
ward field of view without a significant
blind spot.
y Sufficient time should be taken to learn
the “feel” of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. T Driving with a trailer
y You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may re-
sult in skidding or jackknifing and loss of
control. y Avoid abrupt starts and sudden acceler-
ations. If your vehicle has a manual trans-
mission, always start out in first gear and
release the clutch at moderate engine rev-
Never tow a trailer when the tempo-
rary spare tire is used. The tempo-
rary spare tire is not designed to
sustain the towing load. Use of the
temporary spare tire when towing
can result in failure of the spare tire
and/or less stability of the vehicle.
y Never exceed 45 mph (72 km/h)
when towing a trailer in hilly coun-
try on hot days.
y When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. For
safety’s sake, you should employ
extra caution when towing a trail-
er and you should never speed.
You should also keep the follow-
ing tips in mind:

8-24 Driving tips
olution. yAvoid uneven steering, sharp turns and
rapid lane changes. y Slow down before turning. Make a long-
er than normal turning radius because the
trailer wheels will be closer than the vehi-
cle wheels to the inside of the turn. In a
tight turn, the trailer could hit your vehicle. y Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down im-
mediately but gradually. y When passing other vehicles, consider-
able distance is required because of the
added weight and length caused by at-
taching the trailer to your vehicle. 1) Left turn
2) Right turn
y Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn.y If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed im-
mediately by the nearest SUBARU dealer. T Driving on grades
y Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over- heating of your vehicle’s brakes. Do not
make sudden downshifts. y
When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3. y If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat. y If your vehicle has an automatic trans-
mission, place the selector lever as fol-
lows:
Uphill slopes: “D” position
Downhill slopes: A low-speed gear posi-
tion to use engine braking

TParking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-
sion) and shut off the engine.

9-2 In case of emergency
In c ase of e me rge ncyIf you park your vehicle in
case of an emergency
The hazard warning flasher should be
used in day or night to warn other drivers
when you have to park your vehicle under
emergency conditions.
Avoid stopping on the road. It is best to
safely pull off the road if a problem occurs.
The hazard warning flasher can be acti-
vated regardless of the ignition switch po-
sition.
Turn on the hazard warning by pushing
the hazard warning flasher switch. Turn it
off by pushing the switch again.
NOTE
When the hazard warning flasher is on, the turn signals do not work.
Temporary spare tire (if
equipped)
The temporary spare tire is smaller and
lighter than a conventional tire and is de-
signed for emergency use only. Remove
the temporary spare tire and re-install the
conventional tire as soon as possible be-
cause the spare tire is designed only for
temporary use.
Check the inflation pressure of the tempo-
rary spare tire periodically to keep the tire
300117
Never tow a trailer when the tempo-
rary spare tire is used. The tempo-
rary spare tire is not designed to
sustain the towing load. Use of the
temporary spare tire when towing
can result in failure of the spare tire
and/or less stability of the vehicle
and may lead to an accident.
Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechani-
cal damage to the drive train of your
vehicle.

11 - 8 Maintenance and service
Engine oil „Checking the oil level
Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic symbol
“ ” on its top appearing as shown in
the illustration. 1) Notch
2) Upper level
3) Lower level
4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold. „ Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, when towing a trailer, or when
driving in extremely cold weather.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.
B00359
y Use only engine oil with the rec-
ommended grade and viscosity.
y Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If en-
gine oil gets on the exhaust pipe,
be sure to wipe it off.

SAE viscosity number and applicable
temperature
*: 5W-30 is recommended.
Engine oil viscosity (thickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine.
„ Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in ar- eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM (or SL):
SAE viscosity No.:
30, 40, 10W-50, 20W-40, 20W-50
„ Synthetic oil
You can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule.
Cooling system
Use only engine oil with the recom-
mended grade and viscosity.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.
The cooling system has been filled
at the factory with a high quality,
corrosion-inhibiting, year-around
coolant which provides protection
against freezing down to –33 qF
(–36 qC). For adding, use genuine
SUBARU coolant or an equivalent: a
mixture of 50% soft water (or clear
and drinkable water) and 50% phos-
phate or non-amine type coolant.
Use of improper coolants may result
in corrosion in the cooling system. It
is important to maintain protection
against freezing and corrosion,
even if freezing temperatures are
not expected. Never mix different
kinds of coolant.

11 - 3 2 Maintenance and service
yAbnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher. y
Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface bumps and
dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for
the vehicle when fully loaded and for the
vehicle when towing a trailer, adjust the
tire pressures to the values that match
current loading conditions.
„ Wheel balance
Each wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance caus-
es the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle’s straight-line stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not cor-
rectly balanced, have them checked and
adjusted by your SUBARU dealer. Also
have them adjusted after tire repairs and
after tire rotation.
NOTE
Loss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability.
B00051B00052
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of vehi-
cle control could lead to an acci-
dent.
